which can be used to adjust the brightness of mains lights and the speed of AC motors. It uses a triac‚ diac and has a radio-frequency interference (RFI) noise suppression circuit built into it as well. The circuit controls the average power to a load through the triac by phase control. The AC supply is applied to the load for only a controlled fraction of each cycle. The triac is held in an OFF condition for a portion of its cycle then is triggered ON at a time determined by the circuit. Each time

The schematic of an automatic cooler fan for audio amplifiers is given here. The circuit automatically switch ON the cooler fan whenever the temperature of the heat sink exceeds a preset level. This circuit will save a lot of energy because the cooler fan will be OFF when the amplifier is running on low volume. At low volume less heat will be dissipated and it will not trigger the cooler fan ON. The temperature is sensed using an NTC (negative temperature coefficient) thermistor R2. Junction of

AUTOMATIC TEMPERATURE DETECTING SYSTEM Author: NETAJI.PANIGRAHI B.Tech e.mail:netajipanigrahi@gmail.com 1 CHAPTER 1 INTRODUCTION The Automatic Temperature Detecting System is an embedded system application which has the capability of detecting temperature of the environment. The behavior of the system is based on sensor. Based on sensing information the microcontroller will respond. This system works on 5V power supply. Here Microcontroller plays a major role which takes inputs from sensor

steps have been taken so far in these areas. our paper deals with automatic railway gate operation (i.e.‚) automatic railway gate at a level crossing replacing the gates operated by the gatekeepers‚ It deals with two things‚ Firstly it deals with the reduction of time for which the gate is being kept closed and secondly‚ to provide safety to the road users by reducing the accidents. By employing the automatic railway gate control at the level crossing the arrival of the train is detected by the sensors
